It's not just new dating. It's also being by your side at accidental times.
There's also that sort of "love".

You are Tomonaka, the single son of the Kazamidori Cafe.
Each day you're working hard to succeed your parents, creating beautiful-tasting coffee and tea.
One of the shop regulars is an older childhood friend who loves the big size.
She tastes Tomonaka's concoctions every day, and those days never change.

But one day, two girls (class chairman and student president) ask for help with the school festival.

The air is rich with excitement on campus. On these life-altering festival days, a new story begins.
